Optimization of hydraulic drives for parabolic troughs
Andreas Nocker, HAWE Hydraulik SE, Germany
HAWE Hydraulik SE, Munich, engineers and manufactures hydraulic drives (CSPdrives)
for parabolic trough plants consisting of a compact power pack, directional and
control valves, over-center valves, two cylinders and the fittings/hoses for connecting
these components. Optional, but this is depending on the system and the control
philosophy, also a hydraulic accumulator.
An optimized hydraulic drive for a parabolic trough field makes the power plant
operator profit from savings at components, higher system efficiency, lower operational
energy supply needs, less time spent on commissioning and first start-up, lower
maintenance effort and increased life span of the drive and finally also savings on
peripheral and safety devices. Many of shown proposals are even combining two or
more of above mentioned advantages.
